Full vortec system not much power gain

03 g35 vortec

 

Probably just using the big pulley, the little pulley has made over 700whp on one guy's build (very extreme build). 450 is a pretty common number though and that's the hard limit of the stock internals. If you're on the stock rods don't tune over 400whp unless you have a LOT of faith in your tuner though.

EDIT: There are 4 pulley sizes, 3.33" makes about 300whp, 3.25, 3.12, and the smallest is 2.87 that will pretty easily turn 400whp and has a LOT more potential.

 

After two dyno tuning sessions with the 3.12 pulley equipped my G is putting down 380whp on stock internals.

Throttle response is much improved, and overall drivability is better than ever. Highly recommend getting a pro to do the tuning if you have the means.

As alluded to above, was around low 300's whp with the 'big' 3.33 pulley.

 

Thanks for that info I also need to know Two other things where to get the best tune and how much it cost I live in orange county and do you guys have a car show

 

Call around to tuner shops and find out who does UpRev tunes for Nissan cars.

 

I think @Seymore is somewhere in Socal

 

You sure? I thought he was near Tacoma.

 

Thank you for the good advice I will check it out

 

I could be wrong

 

That sounds great I�m definitely going to tune it with Uprev and injectors and 85 and fuel pump and the smaller pulley
